Abstract: [Problem] As a multi-layered sliding member aimed at applications in high temperature regions, there has been proposed slide sheet components each having a metal mesh component such as an expanded metal or wire mesh and an expanded graphite integrated therewith, but a problem remains in the strength when applied to sliding members such as bearings, allowing only a limited range of applications. It is therefore a subject of the present invention to provide a multi-layered sliding member suitable for applications under high temperatures under which lubricating oils or synthetic resins are not adoptable, and to provide a method of manufacturing the same.
